rThis invention relates to improvements in farming implements known as the furrow plow and which embodies among other characteristics means for raising and lowering 7 frhe furrow wheels to regulate the depth of rplementin line with the draft. p

More specifically stated the connecting end of the plow beam isadapted to be steered in line with the draftto obviate sidepulling and overturning of theimplement.

An additional object of the inventionl con-3r sistsV in the provision of means forfregulating the distance between the` furrow wheels,

whereby vthe implementgmay be employed Y for digging-furrowsdifferent widths apart.

. yTith the' above;k and other objects in view, the invention'further consists of the following novel features and details of. construction,

Referring to the drawings in detail, where-` in lilre characters of reference Idenote corresponding parts, the` reference character 10 indicates a plow beam liavin'gia driver seat i one vendand abloclrV 12 withinY the bifurcated forward endl of the plow'beam. A`clevis13, Carried upon the ex-H tended end of the block, is adapted for connections with awagon tongue or other conf y p y l p Y Vconnected at its opposite end with a foot `rest 39. i .i f j nection, such .as indicated at 14. A steering V"shait15, vertically vdisposed within the'l plowV beam, is extended within 'the bifurcation thereforyand the inner most end of the block 12. The purpose of such construction'will be presently apparent. y f

A stopcollar 21, carried by the axle 1 7, is adapted to abut the .end of the' axle sleeve 16 ,adjacent theVA pose'dfrom the stop `collar 21 and/abutting the opposed end of the sleeve 16 terminates to vprovide an arm 23. I A pivoted link 24:, having connection with-fthe-Loutermost end its' opposite'end with` an operating leverl 25 adapted to be shiftedv across'a segment 26 the lever 25ersv extended forconnection with the sliaft28. The aforementioned mounting of the leverY 25 is common to other levers which -will be hereinafter described.

A clevis29, curved throughout itslength, f is laterally projected from the bloc-k12 and khas its ends connected to tlieopposed sidesV of the beain 10r through the instrumentality oflthebracerods 30. ,A'lin'lBL having conwise secured within the innermost extending end of the link 31, whereas its opposite end is yconnected with the beam 34 supporting the clevis 29, is extended rearwardly and to one siderof theplow-beam `10 and which ter-v minates slightly in advance of the sleeve 16. A bar 88., vpassed beneath theI sleeve 16 and yhaving connection atV its forward end with the Vaforementioned endfof'the linkV y3'?, is

offset '118, whereas a-.colla'r 22remotely dis- .Y

A ,lever shaft 28, i 'extended through the Vsleeve 2'?,k has portions `removed within which the innermost end of vnection with oneend of the clevis 29, is atf l 'tachedfto l the underside of the sleeve.j 16 "through the'instrumentality of a U-'bolt 32. 1

turnbuclrle rod 83 is hooked or other- A rear furrow wheel 40, journaled upon the outwardly offset end 41 of an axle 42, journaled within a boxing or other bearing 43, carried by the plow beam 10, is adapted to be disposed to one'side of the plow beam, substantially as illustrated in the top plan view in Figure 2 of the drawings. An anchorage plate 44, secured to one side of the plow beam 10, in oppositely disposed relatlon to the rear furrow wheel 40, depends an appreciable distancetherefrom to facilitate connection of an Lj-shaped lifting arm 45 therewith, as indicated atr46. A crank arm 47, fixed to the uppermost end of the axle 42 by a set screw 48, is interposed between the jaws or bifurcated portionrof a forkedclamp A49 loosely mounted upon the axle. A link 50, having pivotal connection at its upper end with the clamp 49, is eccentrically connectedas at 51, to the L-shaped lifting arm 45. f

A substantially elongated U-shaped plate 52, carried upon the plow beam 10, is adapted to journal the vertically disposed portion of an'axle 53 for a front furrow wheel 54. A crank arm 55, constructed after the manner of the crank arm 47 and fixed adjacent the uppermost end of the Aaxle 53, also supports a loosely mounted forked clamp 56 similar to that as designated at 49 in Figure 4 of the drawings.

' n .Anp L-shaped .lifting lever 57, pivotally 'mounted, as at 58, to the lowermost end of a link 59, pivotallv mounted at its upper end withjthe forked clamp y56, is adapted to swing from the Vpivot 58 when actuated b v a lifting lever 60 throughthe instrumentality f oxfa connecting link61 having connection withA the uppermost extremity thereof. A link 62 is also employed to provide the means of connection between ay turning lever 63 with the free end of the crank arm 47. A separate link 64 is adapted for establishing the means of connection between the aforementioned lever 53 and the crank arm 55. The L-shaped lever 45. operable bv an additional lever 65 through a link 66, is adapted toraise and lower the Arear furrow wheel .4() independently of the front furrow wheel 54, in conjunction with the ground engagling wheel 20 toiset vthe plow shares at de- Y sired depths when traversing uneven or rolling ground. f

As manifest frointhe foregoing description and accompanying drawings, thc U-shaped plate 52 will afford lateral adjustment to the forward furrow wheel 54, whereby the distance between the furrow wheels may be regulated for cultivating fields to be plowed in furrows different depths apart. Y

Colters, vertically adjustable upon the plow manipulation of the entire implement will be experienced.

As mentioned in the foregoing, the block 12 was adapted to follow the wagon tongue 14 when swung upon the steering shaft 15. To this end, I have provided a positive means of connection between the turning lever 63 and steering shaft 15 by a link and arm connection, as best illustrated in Figure 2 of the drawings. Such connection will facilitate simultaneous turning of the furrow wheels in conjunction with that of the block 12, whereby the entire implement would track directly after and in line with the draft to obviate upsetting of the implement by side draft.

. B f the arrangement of the levers upon the sha-fl 28, it is apparent that all of the levers can be simultaneously operated if desired to raise and lower the entire plow in accordance with the depth and pitch of the colters, break-u ers, etc. All of the wheels will, therefore,-' compensate or coact with one another to facilitate execution of the adjustment.

The invention is susceptible of various changes Vin its form, proportions and minorf details of construction, and the right is here` in reserved to make such changes as properly fall within thescope of the appended claim.

Having thus described the invention, what is claimed is A plow construction comprising a beauf' having furrow wheels located adjacent the ends thereof, a land wheel for the beam supporting the other side of the plow, said beam having a bifurcated extremity, a block swingf ably mounted within the bifurcation includ' ing a steering shaft, lifting and turning arms for each of the furrow wheels, mechanically 'operated means establishing operative connection between the steering shaft and turn- `'ing arms to cause the plow to automatically' track after and in alignmentvwith the point of draft, an operating lever cooperatively associated Vwith the rmechanically operated means to manually turn the furrow wheels,

mechanically operated means connected with" the lifting arms to independently elevate the respectivefurrow wheels, and mechanically operated means simultaneously raising and lowering one of the furrow wheels and the land wheel.

In testimony' whereof I affix mv signature.
